System for analyzing material systems

Abstract

The invention relates to a system for analyzing material systems by which a product is achieved which is highly viscous or solid at ambient conditions, the system (1) comprising a processing unit (3) for processing the viscous medium and at least one feeding device (7; 9) for feeding starting materials into the processing unit (3), the feeding device (7; 9) being established such that the amount of the starting material or the starting material can be varied, and the processing unit (3) further comprises an outlet (13) which is connected to a device (15) for producing pellets or test specimens if the product is solid at ambient conditions or to a dosing pump for transferring the product into a collecting vessel if the product is highly viscous at ambient conditions

1 . A system for analyzing a large number of material systems in amounts in a range from 0.001 to 1 kg by which a product is achieved which has a viscosity of more than 10 1  mPas or which is solid at ambient conditions, the system comprising a processing unit for processing the viscous medium and at least one feeding device for feeding starting materials into the processing unit, the feeding device being established such that the amount of the starting material or the starting material can be varied, and the processing unit further comprises an outlet which is connected to a device for producing pellets or test specimens if the product is solid at ambient conditions or to a dosing pump for transferring the product into a collecting vessel if the product is highly viscous at ambient conditions. 
     
     
         2 . The system according to  claim 1 , wherein a separation unit for degassing is arranged between the processing unit and the device for producing pellets or test specimens or the dosing pump for transferring the product into a collecting vessel. 
     
     
         3 . The system according to  claim 2 , wherein the separation unit for degassing comprises a degassing vessel and a vacuum pump which is connected to the degassing vessel. 
     
     
         4 . The system according to  claim 1 , wherein the device for producing pellets or test specimens comprises a dosing unit. 
     
     
         5 . The system according to  claim 1 , wherein the dosing unit or the dosing pump is a gear type pump. 
     
     
         6 . The system according to  claim 4 , wherein a mold for forming the pellets or the test specimens is connected to the dosing unit. 
     
     
         7 . The system according to  claim 4 , wherein the dosing unit is a screw injection machine. 
     
     
         8 . The system according to  claim 7 , wherein the screw injection machine is an extruder or an injection molding machine. 
     
     
         9 . The system according to  claim 1 , wherein the processing unit comprises a processing vessel and the processing vessel and/or the degassing vessel comprise a stirrer. 
     
     
         10 . The system according to  claim 9 , wherein the stirrer is a horseshoe mixer. 
     
     
         11 . The system according to  claim 10 , wherein the horseshoe mixer comprises at least one stirrer blade which is designed such that solid material which deposits on the walls of the processing vessel and/or the degassing vessel is scraped off the walls by the stirrer blade. 
     
     
         12 . The system according to  claim 1 , wherein the processing unit comprises a processing vessel and a vessel holder for changing the processing vessel. 
     
     
         13 . The system according to  claim 12 , wherein the feeding device and the outlet are connected to the vessel holder. 
     
     
         14 . The system according to  claim 1 , wherein the system comprises a cleaning unit for cleaning the processing unit.
